  • OpenWRT based gateway with dnsmasq and internal server with bind

    - by Peter
    I have router based on OpenWRT which has dnsmasq 2.59. Inside my local area network I have a NS server bind. This server has internal and external views for a couple of my domains. My router forwards port 53 TCP and UDP from outside IP (router WAN) to this server. For the external clients everything works fine. In order to organize the internal view, I decided to add the exception to /etc/dnsmasq.conf server=/mydomain1.com/192.168.1.1 server=/mydomain2.com/192.168.1.1 server=/mydomain3.com/192.168.1.1 (192.168.1.1 - IP address of the NS server) According to dnsmasq manstrong text: More specific domains take precendence over less specific domains, so: --server=/google.com/1.2.3.4 --server=/www.google.com/2.3.4.5 will send queries for *.google.com to 1.2.3.4, except *www.google.com, which will go to 2.3.4.5 this domain name with all the sub-domains is supposed to be forward to my NS server. Everything works (SOA, NS, MX, CNAME, TXT, SRV etc.) except for A-record: # nslookup -type=a mydomain1.com Server: 192.168.1.100 Address: 192.168.1.100#53 *** Can't find mydomain1.com: No answer 192.168.1.100 - IP address of my router (dnsmasq) However, I can get the answer for the TXT-record query: # nslookup -type=txt mydomain1.com Server: 192.168.1.100 Address: 192.168.1.100#53 mydomain1.com text = "v=spf1 include:mydomain1.com -all" When I just specify the local IP of my NS server (direct access to the server without using dnsmasq) then the results are: # nslookup -type=a mydomain1.com 192.168.1.1 Server: 192.168.1.1 Address: 192.168.1.1#53 Name: mydomain1.com Address: 192.168.1.1 There is a similar situation with the MX-record: C:\>nslookup -type=mx mydomain1.com Server: router.lan Address: 192.168.1.100 mydomain1.com MX preference = 10, mail exchanger = mail.mydomain1.com mydomain1.com nameserver = ns.mydomain1.com mail.mydomain1.com internet address = 192.168.1.1 ns.mydomain1.com internet address = 192.168.1.1 C:\>nslookup -type=a mail.mydomain1.com Server: router.lan Address: 192.168.1.100 *** No address (A) records available for mail.mydomain1.com This is a dig result: # dig +nocmd mydomain1.com any +multiline +noall +answer mydomain1.com. 86400 IN SOA ns.mydomain1.com. hostmaster.mydomain1.com.

How to manage this problem?

  • USB mouse connecting and disconnecting randomly

    - by Kalec
    I've bought an acer aspire 5742G about 2 months ago or so and it's been running great, but sometimes I used to hear the windows error beep but I had no idea what was causing it since the "bug" was automatically fixed so fast I couldn't even see an error message (also it kinda always happened when I was busy also, either in a game or while doing my homework). Later on my mouse would simply not work for 3-5 seconds then work again, I thought nothing of it at the time. I also had a problem where it only worked in one usb and one only. To move it I had to remove the battery, unplug the laptop and hold the power button for 2 minutes to reset the bios settings. Since today though it went nuts. Sometimes it disconnects / reconnects 12 times in 10 seconds and windows just keeps beeping till I unplug it, then it runs smooth for 5-6 minutes then it goes nuts again. Other times it seems like it skips (disconnects for a fraction of a second) other times just for 2-3 seconds. But this is incredibly frustrating. Sometimes the power just goes down (the laser turns off) and well that at least I would understand but this is a rare occurrence. Now I know the usb ports work since I have a lot of other devices connected and I tried the mouse on a room m8's laptop so the mouse also works. My only conclusion is that it's an operating system / settings bug and / or problem (I have tried the mouse in all ports by the way). All drivers and bios are up to date (maybe except mouse but I can't seem to update that and the mouse has no name, just a serial number which helps with nothing. Still it worked till today and nothing should have changed any way). I have made sure windows can't shut it down to save power (in device management). Also I tried to delete the drivers and re-install them, rebooting and the power button trick but nothing. Most I have done is get rid of the 12 disconnects / reconnects every 10 seconds :) but that's all :( I would buy a new one but I'm afraid it might do the same thing. ****EDIT****** Tried the mouse again at a friend but now it didn't even install it's software nor did the update work. Think I'll just buy a new one but I'd still like a suggestion at least so I'll leave this open #### EDIT 2 Now it works again, I can't explain this. Still thinking of getting a new one though

  • HDD from Mid-2009 MacBook Pro works OUTSIDE laptop, but not INSIDE.

    - by Jaime
    Leading up to the problem: I was working late one night on a Keynote presentation. My battery ran out, and the computer did that hibernation thing it does when there's no battery power. I got my charger, connected it to my computer, and then pushed the power button. It started up for a second in to the gray screen it usually goes to. Then I turned around, tugging the magsafe charger out of the connector on the computer. This caused my computer to shut down again. Now I can't get it to boot at all -- just a blinking folder icon with a question mark in it on boot up. I've tried pretty much everything to deal with this. Multiple forced reboots, resetting PRAM and NVRAM, etc. I booted to original OSX disc and ran disc utility, but I discovered that there is no disc to boot to. I ran the Apple Hardware Test, and it came back 100% good. I booted to an Ubuntu live-boot disc and ran that disc utility, just to see if it recognized a disc at all. It didn't. So I removed the HDD, and replaced it with a bootable volume running BSD. It didn't recognize that HDD either. I then attached my HDD to my computer via an external enclosure with a USB interface. Lo and behold, it booted! So my computer now only work with my HDD attached externally. This means that the HDD is functional. And the AHT returns no hardware malfunctions. So what the hell is going on? … In the meantime: I've put the HDD back into the computer but it still doesn't do anything at all (I'm running it externally right now). I just checked the serial number and my 1 year warranty expired recently, so I can't send it back for repair. … Little Help Thoughts? I've been searching everywhere for leads, but no luck. …

  • Why does my mail get marked as spam?

    - by schoen
    I Have the server "afspraakmanager.be". It matches everything not to be a spam server.(it isn't by the way): it has reverse dns, spf,dkim,... . But hotmail marks it as spam. I think the problem is the SPF/DKIM records. when i sent an email to my gmail it says: "Received-SPF: neutral (google.com: 2a02:348:8e:6048::1 is neither permitted nor denied by best guess record for domain of [email protected]) client-ip=2a02:348:8e:6048::1; Authentication-Results: mx.google.com; spf=neutral (google.com: 2a02:348:8e:6048::1 is neither permitted nor denied by best guess record for domain of [email protected]) [email protected]; dkim=neutral (bad format) [email protected]" So i guess my SPF and DKIM records aren't set up right. But I also don't have a clue what is wrong with them. this is the zone file: ; zone file for afspraakmanager.be $ORIGIN afspraakmanager.be. $TTL 3600 @ 86400 IN SOA ns1.eurodns.com. hostmaster.eurodns.com.

  • apcupsd on Linux does not report on APC BackUPS Pro 900

    - by lserni
    From what documentation I could find, the UPS should be (is!) supported by Linux and ought to work with apcupsd. I looked for specific problems such as the infamous Microlink protocol, and found none. I have found a feedback from a guy in UK that reports using this very model on a not-too-different OS version (his OpenSuSE 12.1, mine 12.3 x86_64). The USB port is detected, lsusb reports Bus 002 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply and lsusb -v -s002:003 confirms and expands: Bus 002 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x051d American Power Conversion idProduct 0x0002 Uninterruptible Power Supply bcdDevice 0.90 iManufacturer 1 American Power Conversion iProduct 2 Back-UPS RS 900G FW:879.L4 .I USB FW:L4 bNumConfigurations 1 Configuration Descriptor: [...] Interface Descriptor: [...] bInterfaceClass 3 Human Interface Device bInterfaceSubClass 0 No Subclass bInterfaceProtocol 0 None iInterface 0 HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.00 bCountryCode 33 US bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 1134 Report Descriptors: ** UNAVAILABLE ** Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 100 Device Status: 0x0000 (Bus Powered) The kernel recognizes this and duly sets up crw------- 1 root root 180, 96 Nov 4 16:11 /dev/usb/hiddev0 As far as I know, everything is as it should be.

This confirms that it's not the Microlink problem, or it would report the battery status, if precious little else. If I disconnect the USB cable, I get an apcupsd message to the effect that communications have been lost; and I get the "communication restored" broadcast too, if I reconnect the cable. apcupsd is monitoring. So everything tells me that it should work -- only it doesn't. Does anyone spot what I'm missing?

  • Win7 x64 unresponsive for a minute or so. HD failing?

    - by Gaia
    On a fully updated Win7 x64, every so often the system stalls for a minute or so. This has been going on for a couple months now. By stalling I mean the mouse responds and I can move windows around, but any window, any program, that is open becomes whiteish when I select it AND any new programs will not open. It doesn't matter what kind of program it is. When the stall stops all clicks I made (open new programs for example) take effect. Nothing shows up consistently (as in every time this happens) in the event log. Today though I was able to find something, but it doesn't reveal much other than the "system was unresponsive". It's a 7009 for "A timeout was reached (30000 milliseconds) while waiting for the Windows Error Reporting Service service to connect." It doesn't matter if I have any USB devices plug-in or not. I've ran Microsoft Security Essentials and Malwarebytes. While the machine is unresponsive, I've noticed that Drive D (the other partition on the single internal HD in this laptop) is displayed like this in explorer. This never occurs with Drive C or any other drive on the machine. . SMART report for the physical drive: Read benchmark by HD Tune 5 Pro, probably the most telling piece of the puzzle. Isn't this alone enough to see there is a problem with the drive, regardless of whether the unresponsiveness is caused by such purported problem? Here is a short hardware report: Computer: LENOVO ThinkPad T520 CPU: Intel Core i5-2520M (Sandy Bridge-MB SV, J1) 2500 MHz (25.00x100.0) @ 797 MHz (8.00x99.7) Motherboard: LENOVO 423946U Chipset: Intel QM67 (Cougar Point) [B3] Memory: 8192 MBytes @ 664 MHz, 9.0-9-9-24 - 4096 MB PC10600 DDR3 SDRAM - Samsung M471B5273CH0-CH9 - 4096 MB PC10600 DDR3 SDRAM - Patriot Memory (PDP Systems) PSD34G13332S Graphics: Intel Sandy Bridge-MB GT2+ - Integrated Graphics Controller [D2/J1/Q0] [Lenovo] Intel HD Graphics 3000 (Sandy Bridge GT2+), 3937912 KB Drive: ST320LT007, 312.6 GB, Serial ATA 3Gb/s Sound: Intel Cougar Point PCH - High Definition Audio Controller [B2] Network: Intel 82579LM (Lewisville) Gigabit Ethernet Controller Network: Intel Centrino Advanced-N 6205 AGN 2x2 HMC OS: Microsoft Windows 7 Professional (x64) Build 7601 The drive less than 1 year old. Do I have a defective drive? Seagate Tools diag says there is nothing wrong with the drive... UPDATE: I noticed that the windows error reporting service entered the running state then the stopped state and the space between the two events was exactly 2 minutes. Which error it was trying to report I don't know. I check the "Reliability Monitor" and it shows no errors to be reported. I've disabled the windows error reporting service to see if the problem stops.

  • DNS settings for resolving Host name to IP not working?

    - by Hasas Ali Khan
    I want to access my IIS hosted application over LAN. First I installed a DNS server. The DNS configuration steps are: Go to DNS Manager - right click on System Name - click on configure a DNS Server. DNS Server wizard open -, click on next button - Select radio button "forward lookup zone" click on next button. In the second window. click on radio button "The server maintains the zone" and then click next. Give the zone name "example.com" Click on radio button, "Do Not allow dynamic updates". and then click next button. In the next window, click on radio button "No it should not forward query" and then click next button. Complete the configure a DNS server wizard and then click on finish button. After it is managing the DNS records: In DNS server wizard. open tree of forward lookup zone and right click on the new zone name "example.com" - properties and click on "Start of authority" and write values on text boxes serial number=1 primary server=systemname.domainname responsible person=hostmaster.domainname Click on server name, highlight domain name, click on edit button and enter IP address of the server where I host my application. Highlight new zone name and right click on it and click "New Host" option. In this window there are three text boxes: Name(user parent name if blank)=scoring Fully Qualified Domain Name=scoring.example.com IP Address= My IP Address and check on "Create associated pointer(PTR) record" and click on "Add Host" Host button and then click done button. I have host header for my application is "scoring" on port 80 and its working fine on server my application setting are I have change its, Advance setting --> Application Pool Identity --> Local System application can access on server with host name "scoring" but it can not access on machines on LAN. When I change LAN machine host file that is under, C:/windows/system32/driver/etc/host and edit it and enter host name with hosted machine IP like this: scoring 192.168.1.20 By making these changes I can run the application over LAN machines as I mentioned above DNS setting by which I can run App over LAN with out editing the client's host file. What mistake am I doing in this configuration?

  • Generating/managing config files for hosted application

    - by mfinni
    I asked a question about config management, and haven't seen a reply. It's possible my question was too vague, so let's get down to brass tacks. Here's the process we follow when onboarding a new customer instance into our hosted application : how would you manage this? I'm leaning towards a Perl script to populate templates to generate shell scripts, config files, XML config files, etc. Looking briefly at CFengine and Chef, it seems like they're not going to reduce the amount of work, because I'd still have to manually specify all of the changes/edits within the tool. Doesn't seem to be much of a gain over touching the config files directly. We add a stanza to the main config file for the core (3rd-party) application. This stanza has values that defines the instance (customer) name the TCP listener port for this instance (not one currently used) the DB2 database name (serial numeric identifier, already exists, they get prestaged for us by the DBAs) three sub-config files, by name - they need to be created from 3 templates and be named after the instance The sub-config files define: The filepath for the DB2 volumes The filepath for the storage of objects The filepath for just one of the DB2 volumes (yes, redundant to the first item. We run some application commands, start the instance We do some LDAP thingies (make an OU for the instance, etc.) We add a stanza to the config file for our security listener that acts as a passthrough to LDAP instance name LDAP OU TCP port for instance DB2 database name We restart the security listener (off-hours), change the main config file from item 1, stop and restart the instance. It is now authenticating via LDAP. We add the stop and start commands for this instance to the HA failover scripts. We import an XML config file into the instance that defines things for the actual application for the customer - user names, groups, permissions, and business rules. The XML is supplied by the implementation team. Now, we configure the dataloading application We add a stanza to the existing top-level config file that points to a new customer-level config file. The new customer-level config file includes: the instance (customer) name the DB2 database name arbitrary number of sub-config files, by name Each of the sub-config files defines: filepaths to the directories for ingestion, feedback, backup, and failure those filepaths have a common path to a customer-specific folder, and then one folder for each sub-config file Each of those filepaths needs to be created We need to add this customer instance to our monitoring scripts that confirm the proper processes are running and can be logged into. Of course, those monitoring config files include the instance name, the TCP port, the DB2 database name, etc. There's also a reporting application that needs to be configured for the new instance. You get the idea. There's also XML that is loaded into WAS by the middleware team. We give them the values for them to plug into the XML - they could very easily hand us the template and we could give them back completed XML.

  • How should I convert a physical drive to a VHD for use with VirtualPC?

    - by RBerteig
    I have the hard disks from a PC that was happily running Windows Me until is it suffered an unknown hardware failure. The drives are intact, and can be mounted and read on other PCs. We have data backups, but there is licensed software installed that may not be possible to migrate to newer versions running on a more modern platform making the idea of just booting a virtual image attractive. Is it possible to make VHDs from the drives such that I can boot them in VirtualPC? If not VirtualPC, would it be possible in any other virtualization tool? Edit: Some more details.... The system was running Windows Me, but upgraded from Windows 95 (or possibly 98). It can't have been more than a Pentium II, but I will have to look at the motherboard to confirm that. There were no "exotic" devices installed, and nothing beyond the usual legacy stuff that would need to survive into a virtual machine. The licensed software did not have a dongle, so I won't need to worry about virtualizing a physical dongle of some kind. Licenses were probably died to the disk serial number. There were two HDs, both IDE. The boot disk is about 6GB, and the spare data disk is 12GB, but nearly empty. I have a small bias in favor of VirtualPC just because its free and I've used it successfully in the past. But this is a good excuse to revisit the state of the art. I do know from direct experience that it is possible to install and boot DOS 5.0 and Win95 in VirtualPC, but the VM extensions weren't available so the experience isn't as seamless as I would have liked. A very old DirectX game that failed miserably under XP SP2 runs really nicely on that VM, and actually plays better in a lot of ways than it did on period hardware, so that gives me hope that this is possible. Edit 2: Well, I'm closer than I was when I asked... so thanks to all for helpful suggestions and hints to what I should be trying. I used WinImage to copy the disks, and VirtualPC 2007 to attempt to boot. So far, I have it booting in safe mode, but hanging with a black screen otherwise. I strongly suspect that the copy of Artisoft Lantastic 8.0 (anyone else remember them?) that is still installed for networking with even older PCs that mostly don't exist any more is the culprit there. In my infinite free time, I will try to resolve the differences between a Safe Mode boot and a normal boot, and feel that it is likely to yield to pressure. I'd accept more than one answer if I could... this isn't as black and white a question as the one accepted answer convention assumes.

  • file corruption on read/write 2.6.32-22-server (happens across many kernels)

    - by Jonathan
    Hi Guys, I'm having an issue where after the server has been up for a period of time (~week/few days) the server will start reading corrupt data. For instance when I run a sha1sum of a file after a fresh boot it remains the same. However after a while I will start to get segfaults and from then on whenever I read this file I get a different sha1sum.

I'm also use KVM for virtualization as well as MD for software RAID on this server and the processor is a Phenom II X4 965. I don't believe it's the software raid however as this affects files also hosted on non-raid partitions so I don't know.

  • Unable to telnet out on port 25 on windows server 2008

    - by NickGPS
    Hi All, I just setup a Windows 2008 R2 server and am trying to get a basic mail server up and running so that I can send emails from my applications. I setup a virtual SMTP server in IIS6 and tried doing a local telnet to port 25, which seemed to work fine. There were no errors during this stage and I can see the mail message appear in the Queue folder. The problem is that mail never leaves the Queue folder.

  • Some questions regarding Hostname

    - by user481913
    I just bought a new VPS hosting plan and i have a few questions. Hope someone here can clear the doubts for me. 1) Is it necessary to have a real domain for a vps hostname? I suppose i can just use a non-real domain like anydomain.com and something like 'server' for the computer name. Therefore i'll end up with something like server.anydomain.com as the vps's hostname. I want to do this for the sake of putting in a hostname to configure the vps to get it going . So, since this non-real domain name does not need to be publicly accessible i don't need to register or own it and instead access the server by the ip address. Is that correct? But i suppose that this also depends upon if my web host allows that? 2)I would also like to run some real sites with real domain names on this vps, so can i just configure the zone file on the primary nameserver and make entries for these domains and point an A record at the Vps's IP to make them publicly accessible over the internet? For example for my 1st domain i could make an entry like this: $TTL 86400 mydomain1.com. IN SOA ns1.mywebhost.com. \ admin.mydomain1.com. ( 2004011522 ; Serial no., based on date 21600 ; Refresh after 6 hours 3600 ; Retry after 1 hour 604800 ; Expire after 7 days 3600 ; Minimum TTL of 1 hour ) server IN A 200._._._ ns1.mywebhost.com. IN A 216._._._ ns2.mywebhost.com. IN A 205._._._ @ IN NS ns1.mywebhost.com. @ IN NS ns2.mywebhost.com. @ IN MX 10 server www IN CNAME server server IN CNAME @ (so this particular line tells the nameserver to point the url mydomain1.com to server.anydomain.com at the particular ip addresss in the A record.... is that right?) Similarly for my 2nd domain i could have a similar entry : $TTL 86400 mydomain2.com. IN SOA ns1.mywebhost.com. \ admin.mydomain2.com. (..... ............................so on........ ......................................... ......................................... ......................................... ......................................... ......................................... Is that correct? 3) Suppose for my vps hostname, i ignorantly chose a domain that someone else alreadys owns , however i think that it won't affect the public accessibility of the real domain or website since only the real owner of the domain has the rights to provide for the nameservers addresses in the TLD registeries through his Domian Registerar? Is that correct? 4)Can i change my vps's hostname later? Would this create any complications?

  • Use windows 7 inside virtual box,as guest i mean, to create a Windows 7 USB using "Windows 7 USB/DVD Download Tool" ? (Linux as host)

    - by Abel Coto
    I want to download the Windows 7 professional iso (x32), from microsoft, and , i can do two things. Or buy a new burner , as mine doesn't work (i am trying to decide what dvd writer i could buy) or use a usb dongle to copy the iso to it , and install it via usb. I want to install Windows 7 in a netbook that now has debian,and in my pc. I think i have to buy only the license for the pc , as the netbook came with windows 7 preinstalled, so i suppose that i can use that serial to activate the windows , although i don't know how to install windows 7 starter instead of professional (i think if you remove a file from the iso, windows let you choose the edition to install). The problem is that in both pcs there isn't any windows , only debian. My father has a netbook with windows 7 starter, but i think it hasn't antivirus (at least until have the Karspersky Internet security for 3 pcs bought ), and i don't trust to make the usb there , if i don't now that there isn't any virus or malware. So i am trying to find a way of Create a Windows 7 usb installation , to at least be able to install windows 7 in the netbook without a external dvd writer. I know that with dd in linux you can copy a debian.iso to the usb , and then install debian with it (i've done it) using something like dd if=win7.iso of=/dev/sdb, but i don't know if this would work for windows 7 iso,and if dd will correctly copy the iso to the usb. I suppose that if you are able to boot and install windows 7 from the usb , is that the method works,and you can forget of problems later with the windows 7 installation (problems because some files could not be copied or like). So , i remembered that Microsoft created a tool to copy the iso to the usb using windows. So i thought that i could install in my pc , virtual box , as i have VT and 8 GB ram in it, and download the iso from microsoft ,install windows 7 in the virtual machine , and then copy the iso inside the machine , donwload the iso tool, and atach a usb to the pc, connect it to the guest , and use the tool to copy the iso to the USB. But i don't now if is possible to use a virtual machine to do this , or the virtualization could give problems with the usb, or something. I have found some minutes ago this How to make a windows 7 usb flash install media, from linux? The first method (dd) is the one i like more , and i trust more ( i don't now if the second method using ms-sys , works well , and if i can trust it. I understand that a iso is like a .rar , but no compressed,only containing the files ,so mount the iso and cp the data inside perhaps is ok. Although the method i like more is the microsoft one (more because is from microsoft , and i suppose they now what they do ,at least with this usb related thing, than anything). Perhaps worth more to buy a external dvd writer haha ... Should the virtual machine method work ?

  • How to rate-limit concurrent sessions with nginx or haproxy?

    - by bantic
    I'm currently using nginx to reverse-proxy requests from web clients that are doing long-polling to an upstream. Since we're doing long polling (as opposed to websockets), when a client connects it will make multiple http connections to the server in serial, re-establishing a connection every time the server sends it some data (or timing out and re-establishing if the server has nothing to say for 10 seconds). What I'd like to do is limit the number of concurrent web clients. Since the clients are constantly making new HTTP requests instead of keeping a single request open, it's a little tricky to count the total number of web clients (because it's not the same as total number of concurrently connected http clients). The method I've come up with is to track http requests by the originating IP address, and store the IP address somewhere with a TTL of 20 seconds. If a request comes in whose IP isn't recognized, then we check the total number of unexpired stored IP addresses; if that's less than the maximum then we allow this request through. And if a request comes in with an IP address that we can find in the look-up table that hasn't yet expired, then it is allowed through as well. All requests that are allowed through have their IPs added to the table (if not there before) and the TTL refreshed to 20 seconds again. I had actually whipped something together that worked correctly this way using nginx along with the Redis 2.0 Nginx Module (and the nginx lua module to simplify the conditional branching), using redis to store my IP addresses with a TTL (the SETEX command), and checking the table size with the DBSIZE command. This worked but the performance was horrible. nginx and redis ended up using lots of cpu and the machine could only handle a very small number of concurrent requests. The new stick-table and tracking counters that were added to Haproxy in version 1.5 (via a commission from serverfault) seem like they might be ideal to implement exactly this sort of rate limiting, because the stick-table can track IP addresses and automatically expire entries. However, I don't see an easy way to get a total count of the unexpired entries in the stick table, which would be necessary to know the number of connected web clients. I'm curious if anyone has any suggestions, for nginx or haproxy or even for something else not mentioned here that I haven't thought of yet.

  • Wirelss card not being detected in backtrack 5

    - by Jesse Nelson
    I just installed backtrack 5 and I am unable to detect my wireless card. iwconfig doesn't list my interface. I can see that the hardware is present in lspci -vnn (see below) but I can't get the interface detected. I have tried to reinstall the compat-wireless package but I get errors during the build (see below) I have done a ton of researching and I keep hitting a brick wall, mostly because the wiki for backtrack is down and I can't find any good resources. Does anyone know how to fix the issue? Also, does anyone no how I can scan the hardware to determine what NIC is assigning my interface? If I can figure out the interface name I think I can set it up manually by putting up the link and using wireless-tools to manually configure the connection, this is what I had to do in arch on my mac. As stated the wiki for backtrack is down and I can't find any help on the issue. I tried to do the full kernel upgrade suggested in my software update but after the update was complete and I logged back in I had a new log in manager and the only thing I was able to log into was window managers. However, after this update my wireless was working fine. Please help I am new to Linux and the wiki is down, I have nowhere else to turn. Forgot to mention I am using the KDE version, not Gnome.

  • Trying to get DNS services running on Windows Server 2008 R2, what am I getting wrong ?

    - by LaserBeak
    Ok, So I am basically trying to get a home server pc up that will provide Domain name services, act as Mail server and web server. I have one static IP, well it's not officially static but hasn't changed in two years so I'll call it static. I have done the following: Configured router NAT/virtual port forward UDP/TCP port 53 to the internal IP of my server 192.168.1.16, in adapter settings specified the manual settings: 192.168.1.16 IP, gateway 192.168.1.1, Subnet: 255.255.255.0 and loopback DNS: 127.0.0.1 Using my public my public IP Checked using http://www.canyouseeme.org/ that port 53 is open and is not being blocked by my ISP. It can see services on this port. Registered Domain name (mydomain.com.au) Updated whois database through the domain registrars site and registered NameServer names: ns0.mydomain.com.au and ns2.mydomain.com.au, both have been associated with my single public IP. (Waited 24 hours) Update the nameserver for mydomain.com.au: primary ns0.mydomain.com.au secondary: ns2.mydomain.com.au (waited 24+ hours) Installed Server 2008 R2, install web server role and DNS role. Webserver works when I enter my public IP into browser of any PC/mobile, get IIS7 welcome page. In DNS server: Created new forward lookup zone: ; ; Database file mydoman.com.au.dns for mydomain.com.au zone. ; Zone version: 10 ; @ IN SOA mydomain.com.au. mydomain.testdomain.com.

  • Logitech Optical Mouse Frozen In Middle of Windows XP Pro Screen

    - by Code Sherpa
    Hi. I have a Logitech Optical Mouse/Keyboard. I have been using them just fine with the system drivers for almost a year now. I recently updated my Kaspersky software and rebooted. Now the mouse is frozen in the middle of my screen. I am not able to login to the Windows XP Pro box that has the frozen mouse (because i can't work the mouse) but am able to remote desktop to this computer. Things I know / have tried: When I boot on the problem computer, I am able to use the keyboard, but not the mouse. I have installed the latest version of Logitech's SetPoint (with the updated drivers) on the problem computer (via remote desktop) and that didn't seem to matter. I bought new batteries for the mouse and that didn't matter. I have tried the mouse/keyboard on another computer and the mouse works just fine there. My suspicion is that the Kaspersky install has overwritten a driver of some sort. Things I have not done (and would appreciate detailed steps if you feel this is the way to go): 1) Uninstalled all the mouse drivers on the machine and reboot. Then, reinstall. Note: When I get to the Device Manager I don't see an option for Human Interface Devices (where the mouse device is). Here are my options: Computer, Disk Drives, DVD/CD-Rom drives, Floppy controllers, IDE ATA/ATAPI, Imaging devices, Network Adapters, Other devices, Ports, Processors, Sound, video, and gaming, System devices, USB controllers. Also, I should point out that Video Controller is the only thing under Other devices and it has a yellow exclamation mark. The same is true for all the items under Universal Serial Bus controllers. I think this means I have to update my BIOS but, since my mouse was working just fine without doing that, I don't think that is my problem. So, how do I get to my Mouse Device? 2) Update my BIOS. Note: As pointed out above, I don't think this matters as my mouse was working just fine under my computer's current BIOS version. Thanks for your help.

  • Windows 7 losing one of my displays after restart

    - by j_kubik
    I have an Intel DZ68BC motherboard with Intel HD graphics card using two monitors (on DVI and on HDMI » VGA). My friend asked me to test if his NVIDIA graphics card works well on my computer (at his it was doing some trouble), so I inserted it in my computer, installed the NVIDIA driver and it worked quite well. Then I removed it, uninstalled everything NVIDIA-related I could find and switched monitors back to my Intel card. Since then after every system start/restart, the system sees only monitor on HDMI » VGA connector, completely ignoring the DVI monitor. I noticed that installing the Intel video drivers causes the system to recognize the second monitor if I don't immediately reboot. After a reboot, the system recognizes only the HDMI » VGA monitor. I also tried starting in safe-mode and using DriveSweeper to remove the remains of NVIDIA drivers. While it seems that some drivers were removed, the situation didn't change. Now I am out of ideas and I really wouldn't like to reinstall the system (again...). I also tried restoring the system to the state before this whole story, but it also didn't change anything. EDIT: I am still trying to troubleshoot this problem. The only point that I could start was driver re-instalation. I traced down the part that restores right settings to a call: C:\Users\Jarek\Desktop\GFX_Win7_64_8.15.10.2696\x64\Drv64.exe -driverinf "C:\Users\Jarek\Desktop\GFX_Win7_64_8.15.10.2696\Graphics\igdlh64.inf" -flags 20 -keypath "Software\Intel\Difx64" This call fixes my displays, and as workaround, I will add it for now to my autorun. I am still looking for better solution anyway... EDIT2: Using DriverView i made a list of currently used drivers both before and after fixing my display using above command. Then i compared logs: No drivers were removed by fixing command. Drivers added by fixing command: MS Remote Access serial network driver (asyncmac.sys) security processor (spsys.sys) Drivers that changed base address (indicates driver-reload?) Canonical Display Driver (cdd.dll) Intel Graphics Kernel Mode Driver (igdkmd64.sys) Monitor Driver (monitor.sys) Added drivers seem rather unrelated to the problem to me, reloaded drivers are just a cnsequence of installing new driver file so there is not much to go here... I really cannot make heads or tails out of it...

  • VPC SSH port forward into private subnet

    - by CP510
    Ok, so I've been racking my brain for DAYS on this dilema. I have a VPC setup with a public subnet, and a private subnet. The NAT is in place of course. I can connect from SSH into a instance in the public subnet, as well as the NAT. I can even ssh connect to the private instance from the public instance. I changed the SSHD configuration on the private instance to accept both port 22 and an arbitrary port number 1300. That works fine. But I need to set it up so that I can connect to the private instance directly using the 1300 port number, ie. ssh -i keyfile.pem [email protected] -p 1300 and 1.2.3.4 should route it to the internal server 10.10.10.10. Now I heard iptables is the job for this, so I went ahead and researched and played around with some routing with that. These are the rules I have setup on the public instance (not the NAT). I didn't want to use the NAT for this since AWS apperantly pre-configures the NAT instances when you set them up and I heard using iptables can mess that up. *filter :INPUT ACCEPT [129:12186] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [84:10472] -A INPUT -i lo -j ACCEPT -A INPUT -i eth0 -p tcp -m state --state NEW -m tcp --dport 1300 -j ACCEPT -A INPUT -d 10.10.10.10/32 -p tcp -m limit --limit 5/min -j LOG --log-prefix "SSH Dropped: " -A FORWARD -d 10.10.10.10/32 -p tcp -m tcp --dport 1300 -j ACCEPT -A OUTPUT -o lo -j ACCEPT COMMIT # Completed on Wed Apr 17 04:19:29 2013 # Generated by iptables-save v1.4.12 on Wed Apr 17 04:19:29 2013 *nat :PREROUTING ACCEPT [2:104] :INPUT ACCEPT [2:104] :OUTPUT ACCEPT [6:681] :POSTROUTING ACCEPT [7:745] -A PREROUTING -i eth0 -p tcp -m tcp --dport 1300 -j DNAT --to-destination 10.10.10.10:1300 -A POSTROUTING -p tcp -m tcp --dport 1300 -j MASQUERADE COMMIT So when I try this from home. It just times out. No connection refused messages or anything. And I can't seem to find any log messages about dropped packets. My security groups and ACL settings allow communications on these ports in both directions in both subnets and on the NAT. I'm at a loss. What am I doing wrong?

  • How to configure sendmail to relay through a specific server

    - by ErebusBat
    I have a tiny home server setup behind my cable modem (bresnan communications). I want to be able for this box to send out email (not receive) for notifications and whatnot. What I have already done: I have installed and configured sendmail. I have added mail.bresnan.net as my SMART_HOST directive. What I belive the problem is When I attempt to send an email I get the following in my mail log: Dec 22 10:24:17 batcave sendmail[1530]: oBMHOHrs001530: from=aburns, size=140, class=0, nrcpts=1, msgid=<[email protected]>, relay=aburns@localhost Dec 22 10:24:17 batcave sm-mta[1531]: oBMHOHWZ001531: from=<[email protected]>, size=397, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1] Dec 22 10:24:17 batcave sendmail[1530]: oBMHOHrs001530: to=<[email protected]>, ctladdr=aburns (1000/1000), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30140, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (oBMHOHWZ001531 Message accepted for delivery) Dec 22 10:24:18 batcave sm-mta[1517]: oBMH9mVv001357: to=<[email protected]>, ctladdr=<[email protected]> (1000/1000), delay=00:14:30, xdelay=00:00:42, mailer=relay, pri=300339, relay=pmx0.bresnan.net. [69.145.248.1], dsn=4.0.0, stat=Deferred: Connection timed out with pmx0.bresnan.net. You can see where the message is accepted for delivery by my sendmail server, then where it attempts to hand off to bresnan's server and it timesout. This is where my question is. Asstute readers will notice that pmx0.bresnan.net is not what I have my SMART_HOST directive set as. This is the (outside?) MX server for the bresnan.com/net domain. Apparently bresnan has their network configured so that you can not access this server from within their own network and instead must use the mail.bresnan.net server (which I can connect to). The problem is that I don't know how to tell sendmail to use this server and not the domain. What I have tried Setting a hosts entry so that the pmx0 server points to the mail IP address. This doesn't work, which makes sense as sendmail is obviously doing an MX query to find the server which returns the IP so there is never a need to do a 'normal' DNS resolve so the hosts file never gets involved.

  • Mac OSX 10.8 Server DNS Domain Routing

    - by Oldek
    I just cant seem to figure out the logic in how to configure my Mac Server. So I have set up an DNS, which will take the domain and all subdomains and point towards an IP. File: db.mydomain.com (in /var/named/) mydomain.com. 10800 IN SOA mydomain.com. admin.mydomain.com. ( 2012110903 ; serial 3600 ; refresh (1 hour) 900 ; retry (15 minutes) 1209600 ; expire (2 weeks) 86400 ; minimum (1 day) ) 10800 IN NS mydomain.com. 10800 IN A 10.0.1.2 www.mydomain.com. 10800 IN A 10.0.1.2 So I want all of these requests to be requested to the 10.0.1.2 server, as I run 2 servers in my cluster. This one has always handled the requests, and now I want to add a server in between. So the server in between will get all the signals from my router which NAT the trafic coming from outside. So after setting this up and trying to point my port 80 towards my new server which will be the middle point, it doesn't work. Is it even possible to do it this way? First server: Mac Second server: Linux So what I try to achieve once more: 1. User goes to mydomain.com or www.mydomain.com 2. User request gets handled by my first server 3. First server refers to a local server, which is only available locally (it is configured to allow requests on port 80 and handle them) 4. Second server receives signal 5. Second server returns a request (either directly send to user or send through first server, whichever is most secure and configurable) I also want to be able to set up domains that lead to other servers in the future, and some that are only available within the VPN. (If that changes anything) I hope some kind soul could help me with this, it is really cumbersome for my mind to get the logic here. Do I have to configure my other server in any way? /Marcus

  • Network unreachable on Ubuntu guest after trying to set up a host only network on Virtualbox

    - by gkb0986
    I have a Mac OS X host and a bunch of guests including Ubuntu and Arch Linux. I was trying to set up a host-only network at eth1 to let me ssh into the system. But now eth0 isn't working properly either. Ubuntu can no longer connect to remote hosts or browse the internet. It tells me that the network is unreachable. What's gone wrong here? I've included some diagnostics below. $ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:10968 errors:0 dropped:0 overruns:0 frame:0 TX packets:10968 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:897264 (897.2 KB) TX bytes:897264 (897.2 KB) Other diagnostic commands and the output: $sudo lspci -n 00:00.0 0600: 8086:1237 (rev 02) 00:01.0 0601: 8086:7000 00:01.1 0101: 8086:7111 (rev 01) 00:02.0 0300: 80ee:beef 00:03.0 0200: 8086:100e (rev 02) 00:04.0 0880: 80ee:cafe 00:05.0 0401: 8086:2415 (rev 01) 00:06.0 0C03: 106B:003F 00:07.0 0680: 8086:7113 (REV 08) 00:0D.0 0106: 8086:2829 (REV 02) $sudo lshw -c network *-network DISABLED description: Ethernet interface product: 82540EM Gigabit Ethernet Controller vendor: Intel Corporation physical id: 3 bus info: pci@0000:00:03.0 logical name: eth0 version: 02 serial: 08:00:27:7d:22:df size: 1Gbit/s capacity: 1Gbit/s width: 32 bits clock: 66MHz capabilities: pm pcix bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=e1000 driverversion=7.3.21-k8-NAPI duplex=full firmware=N/A latency=64 link=no mingnt=255 multicast=yes port=twisted pair speed=1Gbit/s resources: irq:19 memory:f0000000-f001ffff ioport:d010(size=8) $lsmod Module Size Used by nls_utf8 12557 1 isofs 40257 1 vboxsf 43743 2 vesafb 13844 1 snd_intel8x0 38570 2 snd_ac97_codec 134869 1 snd_intel8x0 ac97_bus 12730 1 snd_ac97_codec snd_pcm 97275 2 snd_intel8x0,snd_ac97_codec snd_seq_midi 13324 0 snd_rawmidi 30748 1 snd_seq_midi snd_seq_midi_event 14899 1 snd_seq_midi rfcomm 47604 0 snd_seq 61929 2 snd_seq_midi,snd_seq_midi_event bnep 18281 2 bluetooth 180113 10 rfcomm,bnep ppdev 17113 0 psmouse 97519 0 snd_timer 29990 2 snd_pcm,snd_seq joydev 17693 0 snd_seq_device 14540 3 snd_seq_midi,snd_rawmidi,snd_seq vboxvideo 12622 1 serio_raw 13211 0 snd 79041 11 snd_intel8x0,snd_ac97_codec,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 15091 1 snd vboxguest 235498 7 vboxsf parport_pc 32866 0 drm 241971 2 vboxvideo i2c_piix4 13301 0 snd_page_alloc 18529 2 snd_intel8x0,snd_pcm mac_hid 13253 0 lp 17799 0 parport 46562 3 ppdev,parport_pc,lp usbhid 47238 0 hid 99636 1 usbhid e1000 108589 0

  • OEM sound card with no drivers or support

    - by randy
    I thought my sound card was going out so I bought a sound card online. Everything seemed to work ok, I do have sound. But after a few months, I noticed the extra software that downloaded with the sound card drivers didn't work. I ended up contacting creative and after a month of e-mail support, they asked for the serial number and/or model number. Their reply back was I had purchased an OEM sound card and they could not provide support for that, and informed me that that is why their drivers and software didn't work. They informed me that I had to contact the company that distributed the sound card and install their software. Is there anything I can do to find out who distributed this sound card, or is there anything I can do to get other features to work? I have 4 speakers and a sub but only 2 speakers produce sound. The only control I have is the volume. Creative's driver update program will find my sound card, download updates and even added software, but if I try to click on a downloaded program like Creative's Toolbox or Media Center, I get an error that it cannot find the devise. That is why I contacted creative in the first place. EDIT Thanks for the responses everyone. Here's an update. I thought I'd go thru my old computer stuff for my classes at school. I have a lot of old stuff saved, boxes and cables and stuff. I found the box the sound card came in. It looks like a box you'd buy at the store, like Best Buy or CompUSA. I worked with creative for such a long time, it went past the point of being able to return it to the junk online store this shipped from. The box did have an install CD, so I thought I'd start over to reinstall the drivers and software that shipped with the card. I noticed that the install would uninstall a program, then reinstall it. so I thought things were working out. But no good. Everything still works but the programs were still bad. I'd get an error trying to load them - not found. I'll look on the card the next time I get a chance and see if I can spot any kind of name on it.
